Abstract
The utility model discloses an improved thrust pad surface for a high-voltage three-phase asynchronous motor. A plurality of grooves are centro-symmetrically and uniformly distributed at intervals on the pad surface, and are 10mm wide, 10mm deep and 20 to 30mm long. Due to the adoption of the structure, the motor can well rotate in a working process, the running of the motor at the bearing pad temperature of less than 75 DEG C is ensured, the service life of a bearing pad of the motor is ensured, and the phenomenon that the bearing pad is overheated in the running process of the motor to damage the pad surface and even forcibly stop the motor to influence the production of a blast surface is avoided.
Description
Technical field
The utility model relates to a kind of improved high-voltage three-phase asynchronous motor thrust tiling.
Background technique
High-voltage three-phase asynchronous motor mainly is made up of rotor, stator, bearing, preceding bearing shell, back bearing shell, thrust bearing shoe valve and bearing support etc.; Motor is in running, if bearing bush temperature is too high, continues to rise to 85 ℃ and can cause the tiling scaling loss; Or even by forced-stopping machine, thereby influence blast furnace production.This motor is in operation and mainly has following defective: 1, motor thrust tiling is a coal, costs an arm and a leg, wears no resistance, and maintenance cost is higher; 2, motor if bearing bush temperature is too high, continues to rise to 85 ℃ and can cause the tiling scaling loss in running, or even by forced-stopping machine, thereby influence blast furnace production; 3, thrust bearing shoe valve and rotor thrust face heat up because of the rotor play produces friction fit, or the thrust tiling is inhomogeneous owing to wearing and tearing, and has formed not good oil film, produce the friction of large size contact-type dryness and cause the temperature rising.4, ambient temperature is higher in the machine room, can cause the oil of lubricant oil to change; Lubricating oil viscosity is reduced, and it is bad to cause bearing film to set up, and causes the bearing bush temperature unusual fluctuations.
Summary of the invention
The purpose of the utility model is to provide a kind of improved high-voltage three-phase asynchronous motor thrust tiling, and it is simple in structure, can improve the working lubrication situation of thrust tiling, reduces bearing bush temperature.
The purpose of the utility model is to realize like this; A kind of improved high-voltage three-phase asynchronous motor thrust tiling is centrosymmetric on tiling several grooves is being set uniformly at intervals, and the width of groove is 10mm; The degree of depth of groove is 10mm, and the length of groove is 20-30mm.
Adopt the utility model structure, abundant storing lubricating oil in the groove makes the rotation that motor in the course of the work can be good; Guaranteed that motor bearing shell temperature in operation below 75 ℃, guaranteed motor bearing shell working life to avoid motor in running; Bearing bush temperature is too high; Cause the tiling scaling loss, or even by forced-stopping machine, thereby blast furnace production influenced.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure schematic representation of the utility model.
Embodiment
A kind of improved high-voltage three-phase asynchronous motor thrust tiling, as shown in Figure 1, on tiling 1, be centrosymmetric several grooves 2 are being set uniformly at intervals, the width of groove 2 is 10mm, and the degree of depth of groove 2 is 10mm, and the length of groove 2 is 20-30mm.Adopt the utility model structure, the rotation that motor in the course of the work can be good has guaranteed that motor bearing shell temperature is in operation below 75 ℃; Guaranteed motor bearing shell working life; Avoid motor in running, bearing bush temperature is too high, causes the tiling scaling loss; Or even by forced-stopping machine, thereby influence blast furnace production.
